This 27-cm (10.6-in) gyuto is in suminagashi with a core in aogami 2, a very high-performance non-stainless carbon steel.
It is harder than shirogami because it also contains chrome and tungsten, which also strengthens its resistance to wear.
The blade is hand-engraved by Tanaka San.
The traditional-style handle is in honoki and real buffalo horn.
Beware: this blade can rust, so it must be well dried after use.
